Application filed November 28,

This invention relates to new or improved cap twisting and winding apparatus for twisting and winding in cop or pirn form artificial yarns or threads. of filaments of of formation, usually known as cellulose acetate or other cellulose estersof .cellulo'se ethers continuously with their proby dry spinning, and according ,to the said specifications the threads or yarns may be I cap-spun .and wound-in any desired wound form.

The present invention aims to provide unproved formsof apparatus for the production of cops or pirns on the dry spinning mctier or apparatus. I

1925, "Serial No. 71,882, and in Great Britain. December 23, 1924.

commenced independently of the remainder..

It is to be understood that the slow building feed or lift to members which carry the bobbins, tubes or like thread-carriers,

and that the cap spindles or the said members, as the case may be,

H k may either receive the slow building feed only or may receive both the slow building feed and the chasing motion as before mentioned. When the building feed is imparted to the cap spindles alone, the chasing motionis imparted to I u I .1 l As is known, cops or pirns (hereinafter,

referred to as cop wound packages) are formed by the superimposition of two motions, name an up and down traversing or chasing motion and a'slow progressive feed or lift for building the cop or pirn.

I It is very desirable, in order to reduce waste and to avoid stopping the dry spinning'nltier for: dofiing, that one shall be able to control the starting and stopping of each individual cap spindle,-

the cop or pirn building feed or motionin dividually for each spindle, or at most for two adjacent spindles. J llt is also very desirable to wind at a high ,rate of: speed and to have, in forming the cops or pirns, speeds of traverse ;or chasing motion much higher than; those which are used with ordinary slow moving cop winds of cap spinning worsted frames. lln apparatus according to the present 1nvention, the building feed mechanism is combined with means for putting the feed into and out of engagement or operation for each spindle, (or it may be each palr of adjacent spindles) so that the starting and stopping of the building feed can be con trolled individually for each spindle, or it may be for each two adjacent-spindles), thereby allowing the slow lift for any spin dle'(or .pair of adjacent spindles) to be cam or traversing device.

memberscarrying the cop or pirn tubes,

single or common traversing cam or appa-' ratus to impart therapid chasing motion'to the cops or plrns, or to the cap spindles as may be imparted either to v the cap spindles or the case may be, we preferably employ a line or series of separate traversing bars or membe-rs,,each serving to impart the traverse to two adjacent cops or pirns or to two adjacent cap spindles, as the case may be, or it may be to each individual cop or pirn, or

these traversing bars or members each receiving the traversing or chasing motion from a separate Such employment of separate traversing bars or members permits more readilyof the very rapidup and downtraverse which is required in winding cops or pirns of dry spun artificial thread continuously with their production at high speed as before referred to. In any of the forms of apparatus according to the invention in which the cap spindles receive a building feed motion, the thread guides disposed vertically above the cap spins dles and serving-to lead the threads down to the caps are preferably in connection with the cappindles'or otherwise arranged to rise together with their corresponding cap spindles, so as to maintain the balloon of thread at a constant height in relation to the cap. c

Other featuresof the invention will appear from the succeeding description and from the appended claims.-

The accompanying two forms of 'apparatus aecording to the invention, it being understood that these are given as examples only and are in no way limitative. p I F igs. 1 to 7 illustrate a form of apparatus 1n which thecop' or pirn building feed is I imparted to the cap spindles and the traversmg or chasing motion is imparted to the cops or pirns, While Figs. 8 and 9 illustrate a form wherein the building feed is imparted to" the cops or pirns, the'chasing motion being iniparted to the cap spindles.

The improved forms of cap or pirn winding apparatus shown are supposed as applied on a mtier of the character indicated in the said prior British specification. No. 198023, and U. S. specification Serial No. 615,682, the threads of associated filaments formed in the mtier casing being led from the mtier casing (not shownyand fed to the apparatus for winding the cops or pirns.

Fig.1 1s a diagrammatic sectional side elevation of the first form'of apparatus, showing the thread fed to the cop or pi rn winding device by a feed roller or godet arrangedand drivenin the same manner as indicated in the previou British-s ecification 1'98023 and U. b. speci ation erial No. 615,682. and the whorls of the winding apparatus being also driven in a similar manner to that indi cated in the said specification.

Fig.2 is a front elevation of a portion of the improved cop or pirn Winding apparatus," showing the feed. motion shaft and the chasing motion shaft, and four of the cap spindleswith the means for driving thespindles' from the feed motion shaft and for throwing the feed in and out'for the individual spindles; and also the short traversing bars carrying the whorls and the cop or pirn tubes which co-operate with the spindles, and also the means for imparting the chasingor traversing motion to t hesetraversing bars from the chasing motion shaft. It is understood that the feed motion shaft and the chasing motion shaft may extend for any desired length along the mtier and serve for operating any desired number of cap spindles and caps or cover plates are put on to the housing body the bearnigs or guides for guiding the respective spindles in their rise for ing feed are constituted.

Fig. 7 is a detail sectional view of one of the whorls with its cop or pirncarrying sleeve or tube, andshowing the mounting of the whorl on the short traversing or chasing the build bar, and the cap spindle passing up throughthe whorl and its sleeve or tube.

Fig. 8 is a front elevation of a portion of the cop orpirn winding apparatus according to the second form (wherein the cap spindles receive the chasing motion and the cops or pirns receive the building feed).

Similarly to Fig. 2 this figure likewise showsalong the mtier and caused to rotate at a suitably slow speed, for instance aboutgone revolution per hour. A series of clutches 4 on the shaft 3, one for each spindle 1, and each connected by a chain 5 to a lug 6 or other suitable part bolted or otherwise attached or connected to the corresponding spindle as at 7 (see Fig; 3), enable the cap spindles to be individually put into driving connection with the feed motion shaft 3 at will by throwing in the respective clutches, thus causing the spindles to rise slowly. The clutch may be constituted by a resilient.clutch sleeve adapted to begripped into and released fromfrictional driving engagement with a collar 8 fast on the shaft. 3 by a small cam handle or flever9 (see Fig. 8) pivoted to at bolt 10 passing through lugsll on the clutch sleeve l, this clutch lever vbeing adapted, in' the engaged position, to force the lugs 11 of the clutch sleeve towards each other by a suitable face or projection formed on it, and thereby' to grip the clutch sleeve into engagement, and being adapted, in the released position, to allow the lugs 11 of theresilient clutch sleeve to move away from each other and thereby to release the clutch. The clutch can be engagedand disengaged by hand at any time as required, by means of the clutch lever,9. The clutch lever 9 can also be arranged and adapted to disengage the clutch automatically at the top of the lift of the spindle. For this purpose it may be formed with a nose 12 which comes in contact with the top of the lug 6 on the spindle at about the end of the rise of the spindle, whereupon the clutch lever is caused to turn on its pivot and allow the lugs ll of the resilient clutch sleeve to move away from each other, thereby releasing the clutch. The clutch lever in Fig. 3 isseen still in the engaged position just prior to its nose coming into contact with the lug (3 to release the clutch.

13, 13 are thread guides arranged vertically above theirrespective cap spindles and Q to the cap 2, and hence at a constant tension.

The chasing motion is imparted to the cops or pirns by a series of short traversing bars 18 provided along the length of the mtier,

each corresponding to two adjacent cap spindles 1 which pass up through openings in the traversing bars 18 so that these can traverse the tubes, bobbins or the like on the cap spindles. The whorls 19 for rotating the cop or pirn tubes, bobbins or the like, and driven by cotton banding or the like (20 hi 1) from the whorl driving drum of the'mtier (21 Fig. 1), are carried on the traversing bars 18. They slide and rotate on the cap spindles 1 and impart their rotation to the cop tubes,

bobbins or the like through suitable means, such for example as a sleeve or tube 19 (see 1F ig. 7) fast with the whorl and rotating with it on the spindle and receiving the cop or pirn tube 22, bobbin or the like.

The bars 18 receive their traversing motion from a chasing motion shaft 23 extending the length of the mtier and rotated at any ap propriate speed (e, g. 30 to -80 revolutions per minute). The chasing motion is imparted to the respective bars 18 by cams 24: on the shaft 23, one for each traversing bar 18, these cams "imparting the up and down traversing mo tllll till tion to the corresponding bars 18 through vertical rods 25 working in guides 26, 26 and fired at top to their traversing bars 18 at a pointbetweenthe two adjacent cap spindles 1, and provided at bottom with cam rollers 27 working on the cams 24; Means may be provided for preventing the followers or cam rollers carried by theirod's 25 from jumping the noses of the cams, and for preventing the whorls from leavingthe traversing bars on the down stroke For instance, coiled springs 28 may be fitted round each vertical rod 25 between its bottom guide 26 and the end of the rod 25 carrying the cam roller, for the purpose of preventing the cam roller from g jumping the nose of) the cam, and retaining plates 29 may be provided onthe traversing bars 18 and engaging over the flanges of the whorls 19 toprevent the whorls from leaving the traversing bars on the down stroke.

The cap spindles 1 may with advantage work in housings fixed to the front of theframe member 16 extending all along the front of the mtier, the housings providing the guides 30 (see Figs. 4 to 6) in which'the spindles work in their slow feed or lift, the spindles being free to move vertically, .but being restrained from rotating by reason of the anchorage of the chains 5 to them and of the attachment of the spindles to the' arms 17 carrying the thread guide rods 14.- In the arrangement shown, the vertical guides for each pair of adjacent cap spindles are formed, as to one half of the guides, in 'a I housing body 3g, fixed to the frame member 16, and as to the other half, in caps or cover the upper and lower guides 26 for the vertical U rod 25 that transmits the traversing motion to the traversing bar 18.

The chasing motion shaft 23 and the feed motion shaft 3 are driven at the required speeds by any suitable means, In the arrange ment shown they are driven from the main driving shaft 35 of the apparatus (see Fig, 1) through a chain 36 gearing with a chain wheel 37 (Figs. 1 and 2) on a shaft. 37", from which the drive is transmitted to the chas-, ing motion shaft 23 and feed motion shaft 3 through any ordinary or suitable train of gears which may be contained in a gear box 38 at the end of the mtier. Means may, be provided for rotating the feed motion shaft and/or the chasing motion shaft at difierent speeds as desired, for instance when dealing with different weights of yarn.

1n operation, assuming the chasing motion. shaft 23 to be imparting the rapid traverse to the whorls and cop or pirn sleeves, and the cap spindles 1 to be in driving connection through their clutches 1 with the feed motion shaft 3, the treads fed from the mtier by the feed roller 39 (Fig. 1) are wound into cops or pirns by the combined action of the phasing motion and of the slow lift of the spindles, and at the end of the lift of any given spindle the spindle is released automatically from driving connection with'the on to the whorl sleeve 19" in its place. The

release of the cap spindle from the feed mo- .tion' shaft 3 can also be effected by hand by means of the clutch lever at any desired moment, so that if for any reason or interruption it should be required to dotf a defective or incompletely wound cop orpirn, this can be done at any point of the spindle lift and the spindle be set down again in its bottom position for beginning a fresh cop or pirn. To dofi' a given spindle and start afresh cop or pirn thereon, the spindle, declutched from the feed motion shaft 3 automatically at top 70: plates 32, 32 bolted resiliently on the housing K x y of the lift or by hand as explained, is set in its bottom position, the spindle cap 2 is removed and a fresh cop or pirn tube, bobbin or the like is placed on the sleeve or tube 19 5 of the whorl (Fig. 7), the cap 2 is replaced on the spindle, the clutch 4 is engaged again and the thread is thrown on to the new cop or pirn tube, or bobbin. It will'be seen that any given spindles of the mtier can be doifed 10 'whilethe others are in operation.

. Referring now to the form of apparatus shown in Figs, 8 and 9, 40 represents the feed motion shaft and 41 the chasing motion shaft,

.these shafts extending all along the mtier,

the feed motion shaft 40 being driven at a suitable slow speed and the chasing motion shaft 41 at asuitable speed for the traversing motion as beforeexplained. 42 are the cap spindles with their detachable caps 43. 44 is a fixed bar extending all along the mtier and in which are fixed a row of tubes 45, 45 in which the cap spindles 42 are free to reciprocate vertically in the traversing movement, the spindles 42 passing up through the tubes 45. The-whorls 46 with theirsleeves 47 for receiving the cop or pirn tubes, bobbins or the the bottom frame member 44.

, traversing motion is imparted to each spindle like, are arranged'to slide and rotate on the respective tubes in which the spindles 42 reciprocate, the whorls46 and .cop or pirn sleeves 47 for each pair of adjacent spindles 42 by a corresponding cam 50 on the chasing motion shaft 41 through the medium of a fiat spring 51 or a spring mounted levervprovided with a cam roller 52,these springs being fixed to the frame at their rear end by clamping plates 53 bolted to a longitudinal frame member 53* extending all along themtier; the springs engaging at their front end under 45 a shoulder or abutment 54 near the bottom of the spindle 42, the lowerend of the spindle extending through .the spring and being fitted with retainingnuts 55. The slow building feed-motion is imparted, to each 50 vertical rod 49 from the feed motion shaft 40 by a corresponding cam '56 mounted loose on an axle 57 in abracket 58 on the frame, these cams engaging cam rollers 59 on the vertical rods and being each driven from the feed motion shaft 40 bya worm 60 on this shaft gearing with a worm wheel 61 mounted on 'the axle 57 of the cam, and adapted to be clutched into and'out of frictional driving engagement with the cam by means of a 60 milled hand nut 62 screwing on the outer end of the axle 57 and which, when screwed up against the end of the sleeve '56, of the cam, clamps the cam and worm wheel together 1n driving engagement, and releases 65 them from driving engagement when screwed back. In operation the cap spindles 42 are traversed rapidly through thewhorls46 and cop or pirn sleeves 47 by the cams 50 of the chasing motion shaft 41, and the whorls 46 and their cop or pirn sleeves 47 are slowly raised by the engaged cams 56 driven from the feed motion shaft, 'so that the cops or pirns are formed by the combined motions, the threads being-fed from the mtier to the cap spinning devices as in the previous arrangement, and led to the caps through the thread guides (not'shown in Figs. 8 and 9) above the spindles. At, the top of the lift of any given .bar 48 with its pair of cop or pirn tubes on which the cops or pirns have now been wound, the nose of the cam 56 havingreached its highest point, the cam roller 59 one; vertical rod 49 will drop with the rod 49 and bar 48 to the bottom position. The wound cops or pirns can then be dofied and replaced by empty tubes, bobbins or the like, the cam 56 being unclutched from driving connection with the feed motion shaft. On again engaging the clutch the building feed for the given pair of w'horls and cop or piron tubes is commenced again at the bottom of the feed, and so on. In case of a premature interruption in the winding, due to breakage. of threads or other cause, the corresponding cam 56 can be unclutched from driving engagement and the given bar 48 be lowered to the bottom posit-ion for dofiing the cop or cops concerned or otherwise dealing with the interruption. I

It will be seen that with this arrangement the starting and stopping of the building feed for the cops or pirns can be controlled for a each pair of adjacent spindles independently of the others, so that the feed for the cops or for a given pair of spindles can be started at the bottom of the feed independently of those of the other spindles. The fall of the bar 48 with the caps or pirns when the cam roller 59 drops on the cam 56 at the end of the lift can break-the threads, but if desired, the bars 48 may carry pins such as 63 adapted to catch the revolving balloon of thread at or about the end of the rise of these bars and thereby break the threads.

It is evident that the invention is capableof being imbodied in various constructions, and the drawings and description are therefore intended to be illustrative and not as limiting the invention;
